The trouble with telling tanks W2W pulls are a mandatory norm.

[Kraniel]

I'll kind of repeat myself but ... Why would anyone care so much that tanks do W2W pulls in 60+ or 70+ dungeons though ?

Sure, W2W is the norm in expert roulette, but personally when i jump into leveling roulette or anything that could put me in a lower level dungeon, i don't "expect" tanks do go W2W. If they do, it's better, but if they don't, who cares. To me all dungeons before 80 are casual content, and no one should have to worry about W2W pulls there in my opinion.
